Verified Answer
Frogs differ from humans in possessing:a)paired cerebral hemispheres [...
Human possesses enucleated RBC in mature state. But frog blood has both white and red blood cells which are nucleated. Frog cells do not lack platelets.

Frogs differ from humans in possessing:a)paired cerebral hemispheres [...
Mammals have red blood cells lacking a nucleus. Other vertebrates, such as fish, reptiles and birds, have red blood cells that contain an inactive nucleus. Since carrying oxygen is the primary function of red blood cells, losing the nucleus means that these cells can pack more hemoglobin molecules per unit body weight. Frogs have a nucleus because they don't need much oxygen. Humans don't have a nucleus in their red blood cells because they need more oxygen than frogs, so our red blood cells eliminated the nucleus to fit more oxygen in. Frogs can breathe underwater and in air, so they don't need much oxygen, so their red blood cells didn't eliminate the nucleus.

Nucleated Red Blood Cells in Frogs
Nucleated red blood cells are found in frogs, which is a key difference from humans. Here's why this distinction exists:
Function of Red Blood Cells
- Red blood cells are responsible for carrying oxygen from the lungs to the rest of the body and transporting carbon dioxide back to the lungs for removal.
- In humans, red blood cells lose their nucleus during maturation to make space for more hemoglobin, the protein that binds oxygen.
Importance of Nucleated Red Blood Cells in Frogs
- Frogs have nucleated red blood cells, which means their cells retain their nucleus throughout their lifespan.
- This characteristic allows frogs to have a more efficient oxygen-carrying capacity as the nucleus helps in the production of proteins necessary for oxygen transport.
- Nucleated red blood cells provide frogs with the ability to adapt to different environments and varying oxygen levels more effectively.
Comparison with Humans
- In contrast, human red blood cells lack a nucleus, making them more flexible and enabling them to squeeze through tiny blood vessels.
- The absence of a nucleus in human red blood cells increases their surface area-to-volume ratio, enhancing their oxygen-carrying capacity.
Conclusion
In summary, the presence of nucleated red blood cells in frogs is a unique adaptation that allows them to thrive in diverse habitats and efficiently transport oxygen throughout their bodies. This distinction sets frogs apart from humans in terms of their red blood cell structure and function.
